What are the two main types of aircraft wings?

The correct answer identifies the two main types of aircraft wings as cantilever and rotary wing.

Cantilever wings are those that do not require external bracing to support their weight and loads. This design allows for a cleaner aerodynamic profile and is commonly used in fixed-wing aircraft. The structure of cantilever wings generally supports the loads created during flight through internal support structures, contributing to effective performance and design efficiency.

Rotary wings, on the other hand, are characteristic of rotorcraft, such as helicopters. These wings can rotate around a central mast, providing lift as they spin. This design is essential for vertical takeoff and landing capabilities, allowing helicopters to hover and maneuver in ways that fixed-wing aircraft cannot.

Understanding these types of wings is crucial for grasping the fundamental principles of aerodynamics and aircraft design, as they significantly influence flight characteristics and operational capabilities.
